A running container got deleted automatically.



We had a large container running on an Ubuntu server and all of a sudden the container disappeared




  • O.S : VERSION=16.04.5 LTS (Xenial Xerus)

  • Docker: version 18.06.1-ce, build e68fc7a

  • Storage Driver: aufs

  • Observation: We noticed high memory utilization on the host on that particular day, almost 100%, and the utilization started just 30 minutes before the container disappear incident

    This seems to be a bug report... otherwise what is your question?

  • I am trying to find the root cause for the incident happened in our environment. We were running docker ce 18.02 on this host and on 10-Jan-19, the container got deleted automatically and we have only these logs on the server. We are not able to correlate that incident with the errors in the log file, so seeking advise from experts

  • Is it bug ? does that cause container delete ?

  • A really terrible bug if so! Thanks for explaining. I'll take another look and maybe edit your question a bit later

    This seems to be a bug report... otherwise what is your question?

  • I am trying to find the root cause for the incident happened in our environment. We were running docker ce 18.02 on this host and on 10-Jan-19, the container got deleted automatically and we have only these logs on the server. We are not able to correlate that incident with the errors in the log file, so seeking advise from experts

  • Is it bug ? does that cause container delete ?

  • A really terrible bug if so! Thanks for explaining. I'll take another look and maybe edit your question a bit later

  • I would need experts help here to analyze the logs and give a hint on what would have happened
